It is served at the Park Café on Oasis. [I assume it is served on every ship that has a park café]. I had read so much about this sandwich online, that I knew it was the first thing I had to try for our embarkation lunch! [I might have eaten two!]. I think I had at least one every day after that (sometimes two per day!]

They bake these fresh kemmelweck buns. The roast beef is cut to order and then piled high on these fresh buns. But before that, the server smothers the au jus on the bun. Oh my - soooooo good!
